Test Coverage

Scenario	Expected	Status
Profile with old Installed Apps stack	Legacy stack is hidden	[x]
Portable settings round-trip	Remaining settings serialize and deserialize	[x]
Update refresh	Updates continue without publishing an Installed Apps stack	[x]
Legacy device restore	Device-key restore completes without Installed Apps recovery UI	[x]

Decisions

2026-07-15 — Preserve installation and update management

Context: Installed Apps backup is separate from package scanning, installation, and the Updates screen. Decision: Remove only the private-stack backup, profile presentation, and legacy recovery paths. Rationale: This preserves core app distribution behavior while eliminating the deprecated backup feature.

2026-07-15 — Hide persisted legacy stacks

Context: Existing devices may still contain zapstore-installed-apps events. Decision: Filter the legacy identifier from the private-stack profile list after removing new writes. Rationale: Old data should not reappear as an unnamed or unsupported feature.

Spec Issues

None

Progress Notes

2026-07-15: Removed the backup UI, setting, update publisher, and legacy Amber recovery path. Existing legacy stacks are hidden from the profile. fvm flutter analyze and HOME=/tmp fvm flutter test pass.
